Application filed February 5, 1917. Serial No. 146,708.

To all whom it may concern:

Be it known that I, WILLIAM H. BROWN,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented. certain new and useful Improvements in Oil-Cups, of which thefollowing is a specification.

My invention relates to closures for oilholes and the openings in oil cups through which oil is injected into the cup, or, into the duct leading to the machine parts which are to be lubricated. The principal object.

of my invention is to provide an automatic closing oapor closure which can be readily opened with the stem of an oil can, and; which has means upon it to guide the stem of the oil can to the oil hole and prevent. the stem from slipping out from under the 21 further object of my invention is to provide an oiler, the closure of which may be opened for the injection of oil without requiring any morespace above the oiler when it is thus opened than is when it is closed.

A further object of my invention is to provide an oiler, the closure of which has a limited opening, and which automatically closes as soon as it is released.

A further object of my invention is to provide a novel and improved oiler which can be readily and cheaply manufactured,

and is composed of few and inexpensive.

stem of an oil can being inserted under the vizor of the cap of one of my improved oilers.

Fig. 11 is a perspective view showing the stem of the oil can inserted under the cap in thejposition for injecting oil into one ofmy improved oilers.

Referring to Figs. 1, 2 and 3 of the draw ings, reference numeral, 1, is the body of the oiler having a threaded shank portion, 1*, adapted to be screwedinto a suitably threaded hole in the apparatus to be lubricated. This shank may be left plain for driving 1 into unthreadcd holes, when desired, in a. manner well known in the art. An oil hole, 2, extends through the body of the oiler. -The top of the oiler is inclined, preferably about forty-five degrees to permit the opening of the cap without its occupying more vertical space than is required is closed, and to facilitate the insertion of the stem of an oil can from the side. i v i dis a metal cap or closure for the oiler.

It comprises the top or cover portionwhich isextended in front asshown at 3, and is bent down at the sides as shown at 3 to forma vizor for purposes whichwill be described. The cap, 3, is hinged to the body, 1, by means of the pin, 4, which extends through the side walls of oiler, provided with heads, 4 or other suitable means for retaining" it, in position. i

For the purpose of closing provide a coil spring, 5, which surrounds the hinge pin, 4:, and has one ofits ends at tachedto the cap as shown at 6, while its otherend is extended downwardly and has formed upon it 'a semi-circularloop, 6, adapted to engage the frontand rear walls of the central opening, 2, of the oiler. The loop, 6f, serves also as 'a means by which the spring may be seized and properly posi tionedto admit the hinge pin, 4:, when the oiler parts are being assembled. hen the 5, is given an initial tension so that it always tends toclose'the "cap-Q I prefer to join the top of therear wall of the oiler to the top surface of the body by a curved surface, 1", tangent to the straight portion ofthe top of the body and concentric with the hinge pin, l, and to form the rear end,

3, of the cap also concentricwithhingepin, 1, so that the open-mg the prior will be the body of the and through the flanges, 3*,Sand is the cap, 3, I

are assembled, the spring,

Ill)

completely closed by the cap, 3. The end of the curved portion, 3, of the cap, 3, serves as a limit stop when the cap is opened, by coming into contact with the rear Wall of the body, 1.

It will be seen that cap extension, 3, and

flanges, .3 together form a guide in the to be placed under the vizor without any particular care or accuracy, yet with assurance that the stem will be guided so as to properly inject oil into the cup. None of the existing oil cups with which I am familiar provides a closure having this feature. In some of them the cap projects over the sides and front of the cup, but the depending flanges are also formed both at the sides and front of the cup, or there are no depending flanges at all. I have found my construction to 'be extremely desirable and practical in that it permits the injection of oil into the oiler by the use of one hand only. In other oilers with which I amfamiliar, it is necessary to employ one hand to hold open the cap while the other manipulates the oil can. In other oilers, there is a small projection provided on the cap, under which the stem of the oil can may be placed for opening the cap, but as there areno flanges at the sides of this projection, it is diflicult or=quite impossible to open the cap With the stem of the oil can. In such oilers it is customary to arrange the cap so that it will remain open after it has once been opened until it is closed by the attendant, thus increasing the time and care necessary to operate the oiler and increasing the chances for dirt to enter through forgotten open ca'ps. It will be seen that my construction overcomes these undesirable features and effects a saving of time, preventing annoyance and inconvenience to the attendant, and possible damage to the apparatus which the oiler serves.

In Figs. 4, 5 and 6, I have shown an oiler in which the body, 7, has a round shank, 7, but a square top, 7 to facilitate screwing the threaded shank into the apparatus to which the oiler is to be attached.

In Figs. 7, 8 and 9, I have shown an oiler similar to that shown in Figs. 1, 2 and 3, with the exception that the spring for elosing the cap is formed diflerently, and freaets upon the body of the oiler in a different manner. In Fig. 8 the spring, 8, is

shown formed as a double coil spring having its outer ends, 9, secured to the cap and having its central loop portion, 10, engaging the top, 11, of the rear wall of the body of the oiler. A suitable recess is formed in the top of this rear wall for the reception of the spring loop, 10, under the cap. The spring loop, however, so fills this recess that the cap effectively seals the oiler against the admission of dirt and foreign material. It will be understood that a single coil spring may be substituted for the double coil spring in this form of my im n'ovement.

In Fig. 10, I have shown a conventional perspective of any one of the forms of my invention, with the stem of an oil can being inserted under the vizor for the purpose of lifting the cap.

In Fig. 1-1 I show the stem of the oil can inserted under the cap, the cap open, and the oil can inposition to inject oil into the oiler. It will be seen that the side flanges of the cap act as guides to prevent the stem of the oil can from slipping out from under the cap, while the vizor which projects be yond the body of the oiler, gives the end of the stem of the oil can an opportunity to start to lift the cap. I prefer to incline the top of my oiler in the manner shown, so that the stem of an oil can may be inserted into the opening from one side without requiring more vertical space than is occupied by the oiler when it is closed. By forming the oiler in this way, it is adapted to be used in positions where there are obstructions close above it, and in which oilers having top openings only, can not be em-' ployed to advantage. I do not, however, limit the opening of the cap of the oiler to a horizontal position. It is evident that the cap may be opened'su'iiiciently to receive oil from a position vertically above the cup.

In. addition to serving as a 'means for opening the cap, the overhanging sides and ends of the cap also form ample protection to the oiler against the admission of dirt and water.

It will be apparent to those skilled in the art that modifications of my invention may be made without departing from its scope.

I claim and desire to secure by Letters Patent:

1. In an oil'cup, a body portion having an inclined top surface provided with an oil receiving aperture, a hinge pin extending through the body portion in the angle formed by said top surface and the high side of said body portion, and a closure for said aperture hinged upon said pin and resting upon said top surface, said top surface being cut away at its uppermost end so'as to permit the cap to swing about said pin as a hinge. v

'2. In an oil cup, a body portion having an inclined-top surface provided with .an

oil receiving aperture, a hinge pin extending through the body portion in the angle formed by said top surface and the high side of said body portion, said top surface being rounded at its uppermost end to be concentric with said hinge pin, and a closure for said aperture consisting of a cap resting upon said top surface, and hinged upon said pin, and having the upper portion of its inner surface formed concentric with said rounded end of said top surface to con1- pletely close said aperture and to permit said cap to swing open about said pin as a hinge.

3. An oil cup having a straight tubular body adapted at its lower end to be secured to the apparatus which it is to serve and having an inclined top surface surrounding the oil receiving aperture, the metal of the tubular body being bent inwardly at the top of its high side to overhang a portion of the said oil receiving aperture, a hinge pin extending transversely through the body portion in the angle formed by said inclined top surface and the high side of said body portion, and a closure for said aperture having a cover portion resting upon said top surface and having depending side flanges hinged upon said pin, said cover portion being bent along its rear edge to conform to the bent in portion of said body.

In testimony whereof I aflix my signature in the presence of two witnesses.
